Use our free Child-Pugh Score Calculator to quickly assess the severity of liver cirrhosis. This vital tool helps clinicians determine a patient's prognosis and classify their liver function into Class A, B, or C, crucial for treatment decisions and transplant considerations for chronic liver disease.
Formula:
The Child-Pugh score is calculated by summing points assigned to five clinical parameters:
- Bilirubin: Total serum bilirubin level
- Albumin: Serum albumin level
- INR: International Normalized Ratio for prothrombin time
- Ascites: Presence and severity of fluid accumulation in the abdomen
- Hepatic Encephalopathy: Grade of neurological impairment due to liver dysfunction
Each parameter is assigned 1, 2, or 3 points based on its severity:
| Parameter | 1 Point | 2 Points | 3 Points |
|---|---|---|---|
| Bilirubin (mg/dL) | < 2.0 | 2.0 - 3.0 | > 3.0 |
| Albumin (g/dL) | > 3.5 | 2.8 - 3.5 | < 2.8 |
| INR | < 1.7 | 1.7 - 2.3 | > 2.3 |
| Ascites | None | Mild / Diuretic-responsive | Moderate / Severe / Refractory |
| Hepatic Encephalopathy | None (Grade 0) | Grade I-II (Minimal) | Grade III-IV (Advanced) |
The total score determines the Child-Pugh Class:
- Class A: 5-6 points (Least severe, good prognosis)
- Class B: 7-9 points (Moderately severe, impaired prognosis)
- Class C: 10-15 points (Most severe, decompensated liver disease, poor prognosis)
